Although Cryptococcus neoformans can be seen on India Ink prep, a cryptococcal antigen test is FAR more sensitive. We had a patient early this year (HIV positive) who had a positive II and Crypto. antigen. Even when his CSF cultures had cleared up, the antigen test was positive. It can pick up very low numbers of organisms, so is the test of choice for this organism.
